| Abstract: | Data are presented on the reactions K?p → Δ++ + anything at 10 and 16 GeV/c and π?p → Δ++ + anything at 16 GeV/c. In the K?p reaction, scaling is observed between 10 and 16 GeV/c in the variable M2/s. The scaling occurs at relatively low values of M in marked contrast to the reaction π+p → Δ++ + anything. This result can be explained by duality arguments on a triple Regge picture, since the exchanged reggeon-incident particle scattering is exotic. Comparison of the π?p reaction, which is similarly exotic, with the K?p reaction at the same energy gives further evidence for factorization in pomeron-dominated inclusive reactions. |
